I Bleed Red N Blue

Hey everybody, new to the forums, but a forever Bills fan. Going to the home opener and I need to find a spot to bring my small RV! The RV lot is sold out I believe, and the hammer lot is sold out for RV spots too (I think). So where can I stay Thursday night right around The Ralph, errr The Cap? Does ECC allow overnight parking? Any other private lots around there? RV is quite small, probably has the footprint of a dually truck. Thanks guys!! Go Bills
